I think that 3.18.28 would be fine as it is a supported longterm. I've just upgraded to the 4.1 series which I plan to track until a new longterm has been out for a few months and things lok quiet. 3.19 is very problematic though, as it is no longer supported. I'd sooner "downgrade" to 3.18.28 (which likely has more btrfs backports unless your distro handles them). Or, upgrade to 4.1.19. If you are using highly experimental features like raid5 support on btrfs then bleeding-edge is probably better, but I've found I've had the fewest issues sticking with the previous longterm. I've been bitten by a few btrfs regressions over the years and I think 3.19 was actually around the time I got hit by one of them. Since I've switched to just staying on a longterm once it hits the x.x.15 version or so I've found things to be much more reliable. -- Rich -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
